Abstract: A musical tone generating apparatus utilizing a data compression method is disclosed. A musical tone is sampled and is converted into waveform data (S(n)). These waveform data (S(n)) are compressed into compressed dta (C(n)) by a linear predictive coding method and further by a differential quantization method. The number of bits of each of the compressed data (C(n)) is thus significantly smaller than that of the waveform data (S(n)). Thereafter, a memory (2) stores the thus compressed data corresponding to an attack portion of the tone and a selected part of a sustain portion of the tone. Hence, it is possible to remarkably reduce the memory storage. When generating a musical tone, the memory (2) reads out the compressed data (C(n)) of the attack portion and thereafter repeatedly reads out the compressed data of the selected part. The read-out compressed data are sequentially decoded into the original digital data. Thus, the whole waveform of the musical tone is reproduced.

Abstract: A welding apparatus  (10)  for longitudinally traversing and circumferentially welding within the interior of a tube. A rotating weld tip and gas supplying containing head is mounted on and rotationally driven by a rotor tube  (36)  extending from the end  (90)  of a cylindrical housing  (12)  in which it is mounted. The axially fixed rotor  (36)  is surrounded by and is driven by a helix drive connection  (52,54,56)  to a piston  (20) . The piston  (20)  reciprocates in a cylindrical bore  (14)  within the housing  (12)  in response to selectively applied fluid pressure acting against a spring bias  (26) . A strain gage  (72)  on the spring  (26)  controls the fluid pressure by means of valve ("V") whereby reciprocation of the piston  (20)  rotates the rotor  (36)  by means of the helical groove  (52)  and balls  (54) . The various parts are hollow to accommodate the neces­sary wire conductors  (70,86)  and gas flow. A conductive path between the weld tip  (32)  and outside source of current is supplied through the conductive rotor  (36)  a slip ring  (19)  and wires  (86) .

Abstract: A graphics input tablet has a conductive layer and a resistive layer with contacts (16, 17, 23, 24) arranged one along each edge of the resistive layer. The conductive layer is held at a negative potential relative to the resistive layer so current flows in each contact when localised pressure is applied to a region of the tablet (20) to bring the layers into electrical contact. The currents vary with both position and magnitude of the localised pressure. The position of the pressure is detected from the relative currents in opposed contacts and the magnitude of the pressure is detected from the total current in the contacts. The currents are measured by current sense amplifiers and processed in a computer. Analogue front-end processing of the currents is also possible.

Abstract: In known centrifugal pumps the wear plates arranged on either side of the impeller wheel are bolted to the end walls and/or to the spiral housing. These wear plates are exposed to high bending stresses and must therefore be of correspondingly strong design. Not only is this associated with a high material wastage when the worn plates are changed for new plates, but no wear plates may be used which are composed of highly wear-resistant, very brittle materials. According to the invention, however, these disadvantages are overcome in that the wear plates (2, 3) arranged on either side of the impeller wheel (1) are of disc-shaped design and identical on both sides and in that they are clamped between the spiral housing (6) and the end walls (4, 5) by means of clamping devices. In this way the wear plates are not only very advantageously protected against bending stresses but they can also be exposed to wear on both sides, thereby not only reducing material wastage considerably when the worn plates are changed but also greatly increasing the service life of the wear plates.

Abstract: Mounting structure for apparatus which measures on-line the diameter of cylindrical objects, for example, cigarette filter rods, and systems which employ such mounting structure and apparatus are disclosed. The mounting structure includes a pair of fixed-position spaced-apart support flanges and a support platform positioned between the support flanges and sized and configured to support the diameter-measuring apparatus. The support platform is journally coupled to the support flanges to permit oscillatory motion of the support platform about the longitudinal axis of the filter rod. The support platform includes a spindle which is adapted for mateable engagement within the bore of the diameter-measuring apparatus and defines a cylindrical opening coaxially aligned with the filter rod's longitudinal axis so that the filter rod will longitudinally pass therethrough. The spindle also defines an annular slot transverse to the filter rod's longitudinal axis and positioned so as to be coincident with the plane of the light beam emitted by the diameter-measuring apparatus. In such a manner, the emitted light beam will oscillate within the plane unobstructed by the spindle when the support platform oscillates.

Abstract: A protective relay for detecting faults within a predetermined protected zone of a three phase alternating current electrical power distribution system, of the type which utilizes at least one restraint signal in conjunction with at least one operate signal to generate a net operate signal, generates an operate quantity which is related to a zero sequence component of current flowing in the power distribution system and a second operate quantity which is related to a negative sequence component of the current flowing in the power distribution system. The operate quantities are summed to form an operate signal. An adaptive restraint, which is proportional to a negative sequence component of a phase voltage of the power distribution system, is generated and utilized to provide increased sensitivity to higher resistance ground faults. A portion of a positive sequence component of the current flowing in the power distribution signal is utilized as a restraint signal to prevent the unit from operating on negative sequence currents present during normal load conditions. Adaptive restraint enables the directional overcurrent unit to operate correctly should a second fault occur on the transmission line during the period that one pole is open.
